I recently financed an Alienware X51 desktop and I chose the AMD R9 270 graphics card option. I received the desktop and it works wonderfully, but the AMD graphics card does not have an HDMI output. Instead it has a black plastic piece where it should be, right next to the Displayport. Is there any way to remove this to reveal an HDMI output? The graphics card is advertised everywhere as having an HDMI where the black piece has been fitted. Any help would be much appreciated.
